The slender, wide stem encompassing the leaf stalk is 1 to 3.5 centimeters long. Their ovate-elongated to ovate-lanceolate leaf blades are 5 to 25 centimeters long and 2 to 7 centimeters wide. Its tip is very blunt, the base somewhat heart-shaped to wedge-shaped and eyed. The leaf margin is serrated to double serrated.
